During fast charging of the battery pack: 230mA in +12V 
current

For the SAS 9261 RAID controllers, the operating (thermal and 
atmospheric) conditions are:

•

Relative humidity range is 5 percent to 90 percent noncondensing 
(20 percent to 80 percent noncondensing for the RAID controllers)

•

Airflow must be at least 200 linear feet per minute (LFPM) to avoid 
operating the LSISAS2108 processor above the maximum 
ambient temperature

•

Temperature range: +

10 ° C to +60 ° C without battery backup unit

•

Temperature range: +10

  ° C to +44.5  ° C with iBBU battery backup

The parameters for the non-operating (such as storage and transit) 
environment for these controllers are:

•

Temperature range: 

−30° C to +80° C without the battery backup unit 

•

Temperature range: 0

° C to +45° C with the battery backup unit

All power is supplied to the SAS 9280-8e and SAS 9280DE-8e RAID 
controllers through the PCI Express 3.3V rails and the 12V rail. Onboard 
switching regulator circuitry operating from the 3.3V rails and the 12V rail 
provide the necessary voltages. The following states determine the 
typical current consumption of the controller:

•

State 1: During a hard reset

•

State 2: During a disk stress test

•

State 3: While sitting idle at the DOS prompt

The supply voltages are 12V ± 8 percent (from PCI edge connector only) 
and 3.3V ± 9 percent (from PCI edge connector only).

different voltages.
